BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 612,124, dated october 11, 1898.

Application filed April 29,1898. Serial No. 679,190. (No model.)

To @ZZ whom t may concern.-

Be it known that I, FREDERICK A. SCRAN- TON, a citizen of the United States, and a resident of East Hampton, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Bicycle-Bells, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The Object of my invention is to provide a bell Which Inay be conveniently attached to the frame of a bicycle in position to be Operated by a xture on a moving part, as a wheel; and my invention Consists in the combination of the several parts making up the bell and its operating parts, as hereinafter described, and more particularly pointed'out in the claims.

Referring to the drawings, Figure 1 is a detail view of part of the front fork and of the steering-head of a bicycle, showing my improved bell attached in operative position. Fig. 2 is a detail view, on enlargedscale, of the bracket, the clamp, and base-plate of the bell. Fig. 3 is a top view of the bell and the trip mechanism, on enlarged scale, with parts broken away in section to show construction. Fig. 4 is a detail view showing a modified form of bracket.

In the accompanying drawings the letter a denotes the front fork of a velocipede, and b a wheel having spokes b', these parts being of ordinary construction.

The bell c is attached to the bracket d by means of a post h, riveted to the bracket-arm, to which is also attached a clamp e, by means of which the device as a whole may be removably secured to the wheel-fork.

rlhe base-plate f is pivoted to thebracketarm, preferably on the post h, and a lug d' on the bracket arm extends through the curved slot f in the base-plate, the ends of the slot by contact with the lug d limiting the rotary movement of they base-plate on its pivot. A spring n, attached at one end to a pin on the base-plate and at the other end to the lug d', serves to hold the base-plate nor` mally in a position which lifts the trip-pin fm out of the path of movement of the trip device o. The hammerarm 7c is pivoted on the pin t' to the base-plate and has a trip-pin m, which extends through a slot f2 in the baseplate. The hammer-spring Z holds the hammer-arm and striker so that the latter is out of contact with the gong.

The base-plate of the bell is connected with a device for turning the bell on its pivot, this connecting means being preferably a string extending from a point of attachment on the base-plate to a convenient device for pulling the latter to be arranged at any convenient position, as on the handle-bar of the machine.

The `trip device o is secured to any two spokes of the machine, as by means of a clamp o', made up of the clamp-plates and screws, as illustrated in Figs. l and 3 of the drawings. The trip-pin is preferably provided with a roller to reduce friction.

The Operation of the device is as follows: In Fig. l of the drawings the bell is shown as secured to the farther fork of the wheel, so as to bring the back of the bell into view. The trip device in the forward rotation of the wheel will, unless the base is rotated, pass the bell Without engaging the trip-pin on the hammer-lever. When, however, the baseplate is rotated, the trip-pin is moved down into the path of movement of the trip device o and by the continued forward movement of the wheel the hamIner-lever is swung back, and when the pin is released the recoil of the spring Z throws the striker so that a recoiling blow is delivered upon the gong.

In Fig. l of the drawings a modified form of bracket 1" is shown, the inner end extend ing into the bell, the base-plate f being pivoted thereto at one side.

I claim as my invention- 1. 'A movable base-plate, a swinging hammer mounted on the base-plate, a trip-pin mounted on the hammer,.a trip device, means for 'moving the base to bring the trip-pin into the path of movement o f the trip device, and a gong mounted inoperative 'relation to the hammer.

2. A rotary base-plate, a spring-actuated swinging hammer mounted on the base-plate,

a trip-pin mounted on the hammer, a movable trip device, means for rotating the base- IOO plate to bring the trip-pin into the path of movement of said trip device, and a gong mounted in operative relation to the hammer.

3. A bracket With means of attachment to a support, a rotary base-plate mounted on the bracket, a swinging hammer mounted on the base-plate, a trip-pin mounted on the hammer, a movable trip device, means for rotating the base-plate to bring the trip-pin into the path of movement of the trip device, and a gong mounted in operative relation to the hammer. 4. A rotary base-plate, a gong mounted concentric With the pivot of the base-plate, a spring-actuated swinging hammer mounted on the base-plate, a trip-pin connected with the hammer, a trip device, and means for rotating the base to bring the trip-pin into the path of movement of the trip device.

5. A base-plate fixed against other than rotary movement, a swinging hammer mounted 011 the base-plate, a trip-pin connected with l[he hammer, a trip device, means for rotating the base to bring the trip-pin into the path of movement of the trip device, and a gong mounted in operative relation to the hammer.
